Section 3. Requirements
3.1
Business Requirements
Describe all business requirements for the software.

3.2
Functional Requirements
Customize this subfunction to contain the subfunctions necessary to comprehensively define the
fundamental actions that must take place within the software to accept and process the inputs
and to process and generate the outputs.
Subfunction templates for each of the means of specifying functional requirements are provided
below.
3.2.xf
Function X
When functional decomposition is used as the means of specifying the functional requirements
provide a 3.2.xf subfunction for each function. Each 3.2.xf subfunction should be labeled and
titled appropriately for a specific function, where xf is the appropriate sequential subfunction
number and X is the name of the specific function.
3.2.xf.1
Function X Purpose
Describe the intent of the function.

3.2.xf.2
Function X Inputs
Describe the inputs to the function.

3.2.xf.3
Function X Operations
